Castrol® EDGE® is our strongest engine oil. Advanced full synthetic, it has the strength to maintain a protective layer of oil between engine parts at all times.

Castrol® EDGE®: Our Strongest Motor Oil

Why might you need full synthetic engine oil? Simply because today’s small but powerful engines operate at more than double the internal pressure of the engines made 20 or 30 years ago. This means that the pressure between two moving parts can be as much as 10 tons per square centimeter.

That’s the same as the weight of five cars resting on the point of a stiletto heel: which demands a motor oil with the strength to maintain a thin, protective layer at all times. Castrol® EDGE® is an advanced full synthetic motor oil that is liquid engineered using Fluid Titanium Technology to strengthen the oil, reduce friction within the engine and ensure maximum performance.
